Rift-scale fluid pathways. (A) Map of the basement fault network, with possible fluids migration through faults, and current and hypothetical paleo charge points. (B) WNW-ESE schematic geological cross-section, located on (A), with localisations of potential fluid pathways. (C) NNW-SSE schematic geological cross-section located on (A), showing potential fluid pathways through sedimentary layers, and fault systems.
